Urine erythrocytes 3.2 / uL is normal, quantitative examination of urine erythrocytes 0 to 5 / μL is within the normal range, if the urine erythrocytes more than 5 / μL, it is considered hematuria, the cause of the cause is considered to be related to urethritis, urethral stones, nephritis and so on. Generally normal urine red blood cell content of 0 to 5 / μL, so the urine red blood cells 3.2 / uL is normal. If the content of red blood cells in urine is more than 5/μL mostly consider hematuria, hematuria may be caused by urethritis, urethral stones, cystitis, bladder cancer, chronic nephritis, acute nephritis, ureteral stones, renal tuberculosis, kidney stones, kidney cancer and other diseases. If the examiner does a routine urinalysis with 3.2 red blood cells/uL in the urine, there is usually no need to worry, this is a normal test result. If the patient performs routine urine examination and finds more than 5 red blood cells/uL in urine, he/she needs to consult a doctor in time, and the doctor will choose appropriate measures to treat the cause of the disease.
